DESCRIPTION

The SN65C1167, SN75C1167, SN65C1168, and SN75C1168 dual drivers and receivers are integrated circuits

designed for balanced transmission lines. The devices meet TIA/EIA-422-B and ITU recommendation V.11.

The SN65C1167 and SN75C1167 combine dual 3-state dierential line drivers and 3-state dierential line

receivers, both of which operate from a single 5-V power supply. The driver and receiver have active-high and

active-low enables, respectively, which can be connected together externally to function as direction control. The

SN65C1168 and SN75C1168 drivers have individual active-high enables.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas

Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

Products conform to specications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
